History
History Positioning Systems And Their Introduction Into Precision Agriculture

  • A large country needs to inventory natural resources for resource management purposes (lumber, ores, water, farmland, rangeland, etc.)

  • The enormity of this undertaking and the huge amount of data produced by this inventory

  • It’s 1960 and this thing called a computer is just starting to come into prominence


Canada in the 1960 s
Canada In The 1960’s Positioning Systems And Their Introduction Into Precision Agriculture

  • Computers were big and cumbersome, but, they could store large amounts of data

  • Started gathering data in “themes” or layers

  • Computer printer made maps from dots. Maps were not very good, but they were a beginning

  • Made different maps for different themes

  • Stored information in electronic databases

Gis and gps before the computer
GIS and GPS Positioning Systems And Their Introduction Into Precision AgricultureBefore the Computer

  • During the civil war at Fredericksburg the general used panes of glass to compare creeks with enemy lines.

  • If I want to plant a tomato in my back yard I use “mental GIS” by combining themes to determine the best spot to plant


Computers improve
Computers Improve Positioning Systems And Their Introduction Into Precision Agriculture

  • Computers continued to improve

  • More memory

  • Smaller

  • More processing power

  • Cheaper


Gis programs improve
GIS Programs Improve Positioning Systems And Their Introduction Into Precision Agriculture

  • In the 1990’s, GIS Programs improve

  • ESRI Arc/Info

  • LT Plus

  • Grass

    • Uses a special UNIX system computer

  • ESRI Arc/View

    • Can be done on a PC


Computers and programs
Computers and Programs Positioning Systems And Their Introduction Into Precision Agriculture

  • Computers improved and GIS programs improved

  • Without the computer, GIS programs would not have improved

  • Computers got cheaper and more available

  • Programs got cheaper and more available


Today
Today Positioning Systems And Their Introduction Into Precision Agriculture

  • GIS programs can combine spatial and non-spatial data

  • DOQQ’s (corrected aerial photos)

  • Existing maps or digitized maps

  • Satellite Imagery

    (Infrared, thermal)

  • All types of databases (weather, soils, land use, pesticide history, fertilizer history, crop history, etc.) can be combined into one database


Global positioning systems
Global Positioning Systems Positioning Systems And Their Introduction Into Precision Agriculture

  • Developed by Department of Defense

  • Use 27 satellites to pinpoint position

  • Selective availability (scrambling) has been discontinued.

  • Can be mounted of agriculture equipment to monitor yields and make Variable Rate Application of chemicals and fertilizers possible.


Precision agriculture
Precision Agriculture Positioning Systems And Their Introduction Into Precision Agriculture

  • Combines GIS, GPS and VRT technology with agriculture

  • Available to farmers

  • User friendly

  • Online Classes (www.esri.com)

    • Cost of courses online $40.00 - $100

  • Affordable


Site specific technologies
Site Specific Technologies Positioning Systems And Their Introduction Into Precision Agriculture

  • Develops specific programs for crops and range land

  • Free Programs valiable to farmers over internet.

    • www.agronomix.mb.ca

  • SST

    • Company based to write Ag. programs and compile information for farmers.


The future
The Future Positioning Systems And Their Introduction Into Precision Agriculture

  • Sensors improve
